Description
CONVEYOR CHAIN LINK, CONVEYOR CHAIN AND DRIVE WHEELFOR A CONVEYOR CHAIN TECHNICAL FIELD The present invention relates to a conveyor chain link having an improvedwear resistance, a conveyor chain comprising a plurality of such conveyorchain links and a drive wheel adapted for such a conveyor chain. Theconveyor chain link is adapted to be used in a conveyor system comprising an end|ess chain.BACKGROUND ART Conveying devices, such as those which are used for moving objectsbetween different stations in a factory, usually comprise a conveying trackin the form of a belt or a chain. The conveying tracks can be recessed in atrench with vertical side surfaces. Alternatively, they can be located on thehorizontal upper surfaces of the trench or arranged in some other way.The objects to be conveyed are arranged slidably in relation to theconveying tracks, either directly or via supporting means. Larger objectsare often conveyed on supporting means also known as pallets, andsmaller objects may be conveyed using a small carrier often referred to as a carrier puck.
The conveyor chain is forwarded by a drive unit comprising a motor. Theconveyor chins runs in conveyor beams and glides on slide rails attachedto the conveyor beams. Both the conveyor chain and the slide rails may bemade from a low friction material in order to reduce power consumption, toreduce wear and to reduce noise caused by vibrations. ln the forwarddirection, i.e. when the chain transports objects, the underside of theupper body bears on upper slide rails of the conveyor beam. ln the returndirection, i.e. when the chain travels upside down in the return path, theupper side of the conveyor chain may be supported by a bearing surface on which the conveyor chain glides. The conveyor chain may also beprovided with tabs or protrusions by which the chain may bear on an inner slide rai| of the conveyor beam.
One problem with a sliding contact between the conveyor chain and theconveyor beams is that friction is created. The use of low friction materialsin the chain links and in the slide rails reduces the friction. lt is howevernot always possible to select a low friction material for the conveyor chain.Further, dust and other particles may set on the contact surfaces whichlead to a higher friction and thus to a higher wear. Further, the sliding contact induces noise. ln US 5,402,880 an article carrying chain is disclosed. The chain is to beused in an article conveyor and it includes a plurality of interconnectedmoulded plastic chain link assemblies each having a planar top plate. Aplurality of upper and lower tabs formed along the lower portions of thechain link assemblies serve to guide the chain relative to a pair of guiderails of the conveyor frame while permitting free removal of the chain linkassemblies from the guide rails at selected areas along the length of theconveyor and also restraining the chain between the guide rails at other portions of the conveyor such as at curves or vertical bends.
US 6,364,094 discloses a conveyor system comprising a conveyor chain,a chain guidance means and a guide support means. Each chain linkcomprises a link member, a connecting pin and a bearing element. Thelink members are provided with protrusions having through holes, adaptedto hold the connection pin for the conveyor chain. Further, the conveyor chain will slide on the protrusions in the return path.
FR 2629804 and DE 101 51 863 describe further examples of similar conveyor chains.
These solutions work fine in some systems, but are anyhow subjected tothe above mentioned problem. There is thus still room for improvements.
DISCLOSURE OF INVENTION An object of the invention is therefore to provide an improved chain linkthat allows for a reduced wear. A further object is to provide an improvedchain link that will reduce induced noise in a conveyor system. A furtherobject of the invention is to provide a drive wheel that is capable of driving a conveyor chain comprising a plurality of inventive chain links.
The solution to the problem according to the invention is described in thecharacterizing part of claim 1 for the chain link. Further claims are directedto a conveyor chain, a drive wheel and advantageous embodiments and further developments of the chain link. ln a conveyor chain link provided with an upper body having a carryingsurface, and a lower body having a front end and a rear end, where saidrear end is provided with a first leg and a second leg arranged at a certaindistance from each other such that the front end of a chain link fitsbetween the first and second legs of an adjacent chain link, where saidfirst leg has a first protrusion facing outwards from said first leg and wheresaid second leg has a second protrusion arranged opposite said firstprotrusion and facing outwards from said second leg, where said firstprotrusion is provided with a first through hole and said second protrusionis provided with a second through hole being coaxial with the first throughhole, where the first and second through holes are adapted to hold aconnecting pin, the object of the invention is achieved in that the firstprotrusion is provided with a first tab extending towards the front end andthe second protrusion is provided with a second tab extending towards thefront end, where the bearing surfaces of the tabs are parallel with the carrying surface of the upper body.
By this first embodiment of the chain link according to the invention, thechain link will provide a larger bearing surface for the conveyor chain whenthe conveyor chain travels in the return path. The larger bearing surfacewill in turn provide for a lower surface pressure which will reduce thefriction and thus also save energy. Further, the enlarged bearing surfacewill allow for a reduction of the noise induced by the conveyor chain. Thereduction of induced noise is due to the fact that the bearing surface islonger in the travel direction of the chain, which allows for a more stabletransportation of the chain links. The larger bearing surface comprisesmore material which will prolong the life of the chain link due to wear. ln an advantageous development of the invention, the length of the tab isgreater than the radius of the protrusions. ln this way, the length of thebearing surface will be longer than for a chain link without a tab, which willallow for a reduced friction, reduced wear and a reduced noise induction. ln an advantageous development of the invention, the thickness of the tabis greater than the lower wall thickness of the protrusions. Preferably, thethickness of the tab is greater than or equal to the upper wall thickness ofa protrusion. ln this way, more material is provided at the bearing surfacewhich will prolong the life of the chain link. ln the inventive drive wheel, each notch is adapted to fit a chain linkhaving a tab. Each notch is thus provided with a cut-out, where the size ofthe cut-out is larger than the tab of the protrusions of each chain link. lnthis way, a conveyor chain comprising tabs can be driven in a secure and reliable way.BRIEF DESCRIPTION OF DRAWINGS The invention will be described in greater detail in the following, withreference to the embodiments that are shown in the attached drawings, in Which Fig. 1 shows a front perspective side view of a chain link accordingto the invention, Fig. 2 shows a rear perspective side view of a chain link according tothe invention, Fig. 3 shows a side view of a conveyor chain according to theinvention, and Fig. 4 shows a perspective side view of a drive wheel according to the invention.MODES FOR CARRYING OUT THE INVENTION The embodiments of the invention with further developments described inthe following are to be regarded only as examples and are in no way to limit the scope of the protection provided by the patent claims. ln Figs. 1 and 2, a chain link 1 which can form a part of a conveyor chainis shown. The chain link has an upper body 2 with an upper carryingsurface 20 adapted to carry objects that are to be conveyed. The uppercarrying surface is preferably shaped like a substantially flat surfacehaving a plurality of notches 22 and teeth 23 arranged adjacent to the frontend 4 and the rear end 5. The notches and the teeth are arranged to meshwith the corresponding notches and teeth of an adjacent chain link.
The chain link is further provided with a lower body 3 which has a frontend 4 and a rear end 5. The front end 4 has a substantially sphericalbearing seat 16 which is arranged to cooperate with a bearing element 17by partly embracing the bearing element which can be seen in Fig. 3. Therear end 5 has a first leg 6 and a second leg 7 arranged at a certaindistance from each other, with the legs bifurcating out from the front end 4.The distance between the first leg and the second leg is such that the frontend of a chain link fits between the first and second legs of an adjacent chain link when mounted in a conveyor chain.
The first leg 6 has a first protrusion 8 arranged substantially perpendicularto the travelling direction of the conveyor chain and facing outwards fromthe first leg. The protrusion is advantageously utilised as transportfacilitating means, i.e. used as engagement means for cooperation with adrive wheel or the like, for example interacting with a cog wheel of aconveyor drive unit. The protrusion is further advantageously adapted tofunction as a sliding surface bearing on a slide rail in the return path of aconveyor chain. The first protrusion 8 has a first through hole 10 of a non-circular cross-section, preferably substantially triangular. The second leg 7has a second protrusion 9 arranged opposite to the first protrusion 8 andfacing outwards from the second leg. The second protrusion 9 has asecond through hole 11 substantially coaxial with the first through hole 10of the first protrusion 8 and of the same cross-section. The protrusionextends uniformly such that the protrusion resembles a tube shapedprotrusion. ln this way, the connecting pin adapted to be inserted into thethrough holes will be securely fastened due to the large contact surface ofthe protrusion.
The bearing element 17 is partly shown in Fig. 3 and comprises asubstantially spherical main body having a third through hole 18 of a non-circular cross-section corresponding to the cross-section of the firstthrough hole 10 and the second through hole 11. The bearing element 17is arranged between the first leg 6 and the second leg 7. A force absorbingelement 21 is arranged on the side of the bearing element 17 which facesthe rear end 5 of the chain link 1. A connecting pin 19 is arranged to beinserted into the three trough holes 10, 11, 18 to securely hold the bearingelement 17 in position in the travelling direction of the conveyor chain. Thecross-sectional shape of the pin 19 corresponds to the cross-section of thethree through holes 10, 11, 18. The two ends of the connecting pin 19 mayadvantageously be chamfered to facilitate insertion into the through holes.ln this way, a conveyor chain is securely held together by the bearingelements and the connecting pins.
The cross-section of the through holes 10, 11, 18 and the connecting pin19 is advantageously substantially triangular. By shaping the throughholes such that a flat part of the triangular hole is parallel with the uppercarrying surface, the amount of material at the bearing surface 14, 15 of aprotrusion can be maximized. The upper thickness d1 of a protrusion canthus be made larger than the lower thickness d2 of a protrusion where apointed part of the triangular hole is positioned.
The protrusion 8 is further provided with a tab 12 extending towards thefront end 4 of the chain link. The tab extends from the upper side of theprotrusion and the main purpose of the tab is to extend the bearingsurface 14 of the protrusion along the travel direction of the conveyorchain. The bearing surface 14 is parallel with the upper carrying surface20. The width of the tab is preferably the same as the width of theprotrusion. The length I of the tab is preferably in the same range as theradius of the protrusion. ln this way, the bearing surface 14 is enlarged.The protrusion 9 is provided with a tab 13 in the same way.
The tab gives several advantages compared with conventional chain links.The tab provides a larger bearing surface for the conveyor chain which willprovide for a lower surface pressure. The lower surface pressure willreduce the friction and thus the wear on the bearing surface. The reducedfriction will in turn will save energy. Further, the enlarged bearing surfacewill allow for a reduction of the noise induced by the conveyor chain, sincethe longer bearing surface of the chain link will allow for a more stabletransportation of the chain links with less vibration. Since the largerbearing surface comprises more material, the life of the chain link will beprolonged, i.e. more material has to be worn off before the chain link mustbe replaced. The tab can also be used as a wear indicator. By detectingwhen the chain link is worn such that the tab is worn off, an indication that the chain link needs to be replaced is provided. The detection can be made visually by an operator or a photo detector can be mounted in the conveyor system.
By manufacturing the conveyor chain link of a material having a lowcoefficient of friction, such as an acetal plastic and/or polyamide, a costadvantage and a more favourable modulus of elasticity is achieved.
Fig. 4 shows a drive wheel adapted to drive a conveyor chain comprisingchain links where the protrusions are provided with tabs. The drive wheel30 is provided with notches 31 along the circumference of the drive wheel.The notches are semi-circular and are at one side of the notch providedwith a small cut-out 32 such that the tab of the chain link can fit in theopening. The cut-out is advantageously larger than the tab such that thetab will not touch the walls of the cut-out. ln this way, the protrusions of thechain link will take up the load from the drive wheel when the conveyorchain is driven. A further advantage of this solution is that conventionalconveyor chains, where the protrusions are not provided with tabs, canalso be driven by the same drive wheel. The drive wheel is preferably manufactured from a metal material which is relatively wear-resistant.
The invention is not to be regarded as being limited to the embodimentsdescribed above, a number of additional variants and modifications being possible within the scope of the subsequent patent claims.
